## Verdicts

**LanceDB.** Embedded, no server, and tables can live directly in S3, GCS or Azure storage. No self-serve hosted API. Enterprise is sold through a contact form.

**Pinecone API + MCP.** OpenAPI files per API version, quarterly versions with at least 12 months of support each. Nine regional incidents between 9 July and 28 September 2026, four lasting more than an hour.

## Before you call either

### LanceDB

1. Use it through the Python or TypeScript library. There's no public endpoint an agent can call without an Enterprise deployment
2. Build an FTS index before calling `query_type="hybrid"`, or hybrid search has no keyword side
3. Call `optimize()` after many small writes, since each write adds a new file version
4. Use `select()` to drop the vector column from results unless the task needs it
5. On object storage, set a read consistency interval if several processes write the same table

### Pinecone API + MCP

1. Send `X-Pinecone-Api-Version: 2026-07` on every call. Without it you get the oldest supported version
2. Queries go to the index host from `describe_index`, not to api.pinecone.io
3. Wait a few seconds and retry when fresh upserts don't show up in search
4. Back off exponentially on 429. There's no `Retry-After` header
5. Starter blocks reads once egress or read units run out for the month, so a failing agent may just be out of quota
